"Kids, going to the vets now, try not to kill each other!" Lois announced as she left the house with Peter and Stewie to watch Brian have a crucial leg operation, which could take hours.

An hour into the kid's alone time Chris heard an animous moaning noise coming from Meg's room, suspecting the Evil Monkey was hurting Meg, he ran upstairs to help her, instead he discovered Meg using Lois' deodorant can as a dildo, shoving it into her cunt, so much so, she didn't even notice Chris had been there, slowly jerking off to the beautiful sight of his own big sister fucking herself.

After about 10 minutes, Meg calmed down enough to realize Chris had been there and making a gooey mess all over her carpet. "Ahhhhh!!! Chris, what are you doing!!!" Meg screamed.

"Haha! Meg masturbates! And I'm telling mom you used her deodorant!" Chris gloated. Meg froze with fear, not knowing what Lois would do.

Chris thought about it for a while, ultimately coming up with an answer, "Okay, I won't tell mom, as long as you help me finish my work!"

Meg looked confused, not knowing what to think, "What work, mom didn't set any chores." But then she realized, she looked at Chris holding his huge 7-inch cock, she'd heard mom and dad talking about it, but never expected it to be that big!

Meg then began to take Chris' cock into her hand, she slightly stroked it, gradually taking it into her mouth, she began licking the head, teasing Chris, making him moan for more, she began to suck the head like a lollipop while she cupped his hairy balls in her hands. She began bobbing her head up and down, letting her lips do the work, feeling the sweat from Chris fall onto her tongue, eventually the cum came and Chris let out a moan in his croaky voice, the whole house could have heard, maybe more!

Chris then began to take control, he used his huge weight to flip Meg onto her front of her bed. "Oh Chris, don't tease me, just do it!" Meg begged. Chris then began to slowly shove his slightly lubricated cock into Meg's pussy, which was not so tight following her fun with the deodorant can.

Chris then began to hump her like mad, going at a million miles an hour, letting Meg feel the thickness of it, to which Meg had never experienced, not even from the jocks at school who would take her if they were desperate. Meg began to ooze fluid, only lubricating Chris even more, as she screamed to climax, Chris, realizing he was about to blow, quickly asked Meg, "For the love of the flying spaghetti monster, please tell me you took the pill today!!!!!!"

Chris quickly obliged without a second to spare cumming on Meg's face as soon as she was facing him, and moaned as he laid his cock on her huge tits, with a devious smile, cumming with a loud climax, they could set off alarms.

Now, Meg and Chris laying together, naked, Meg covered with cum, caught their breath, where they gave their 'I loves yous' only to look out Meg's window and to hear a familiar sounding, "Gigitty Gigitty, Alriiiight!!!!!"

The End
